Description
[ Major Update : Complete Course updated on December 2024 ]Learn the new Java 8, Java ll, Java 17, Java 21 Features by coding it,This is a pure coding course and you will get a complete understanding of all the Java 8, Java ll, Java 17, Java 21 features by coding itWhy Should I take this course ?This course will help the Java developers to build their knowledge on the new Java 8 featuresAll the new features such as Lambdas, Streams , Optionals, Functional Interfaces and Parallel Programming will be explained via codeThis course will give you the confidence on implementing new Java 8 features in real Java projectsBy the end of this course you will have a complete understanding of new Java 8 functional featuresCourse Overview :Section 1 - Getting Started:This section explains about what will be covered in this courseSection 2 - Why Java-8 ?:This section covers Why Java 8 is important?This section explains about difference between Imperative Programming and Declarative ProgrammingSection 3 - WorkSpace Setup - Mac/Windows:This section covers the installation of Java and IntelliJ in Mac and WindowsSection 4: Introduction to LambdaThis section covers the Why Lambda is needed , Lambdas Syntax and How to implement Lambdas ?Implement the Runnable interface using LambdasImplement the Comparator interface using LambdasSection 5: Lambdas and Functional InterfacesThis section covers the new Functional Interfaces that got introduced as part of Java 8Consumer Functional InterfacePredicate Functional InterfaceFunction Functional InterfaceSupplier Functional InterfaceSection 6 : Constructor and Method ReferencesThis section covers the new Method Reference and the Constructor ReferenceHow Method Reference simplifies the codeHow to use Method reference along with LambdasHow to use Constructor Reference to create new objectsSection 7 : Lambdas and Local variables ( Effectively Final )This section covers the local variable and how it should used in LambdasDefinition of Effectively Final scope of a variableSection 8 : Streams APIThis section covers the Streams API which is one of the important feature that got introduced as part of Java8How the Stream API Works Internally ?How Collections are different from Streams ?How to debug a Stream ?Section 9 : Streams API OperationsThis section covers different Streams API operations that can be used in Streams to achieve an objectiveStreams Operations such as :map()flatMap()distinct()count()filter()reducer()Map, Filter and Reduce patternmax()min()limit()skip()allMatch(), anyMatch() and noneMatch()findAny() and findFirst()Explanation of Stream operations that are Short Circuit operationsSection 10 : Streams API - Factory MethodsThis section covers different Streams API factory method that can be used to create StreamsSection 11: Numeric StreamsThis section covers the Introduction to Numeric Streams which can be used to perform some numeric related operationsSection 12: Terminal Operations StreamsThis section covers different way to collect the data from the Streams PipelineTerminal Operations such as :joining()counting()mapping()max(), min()sum()average()groupingBy()partitioningBy()Section 13: Streams API - Parallel ProcessingThis section covers how to perform the Parallel processing using StreamsHow Parallel Programming makes use of the processors in your machine to perform concurrency operations?How Parallel Programming works internally ?How to check the performance between the sequential and parallel programming ?Scenarios when not to use parallel programmingSection 14: OptionalThis section covers What is Optional and the benefits of OptionalHow Optional can help you avoid Null Pointer exceptionExploring the different operations that are part of Optional such as :empty()ofNullable()of()orElse()orElseGet()orElseThrow()isPresent()ifPresent()map()flatMap()filter()Section 12: Streams API - Parallel ProcessingThis section covers how to perform the Parallel processing using StreamsHow Parallel Programming makes use of the processors in your machine to perform concurrency operations?How Parallel Programming works internally ?How to check the performance between the sequential and parallel programming ?Scenarios when not to use parallel programmingSection 13: OptionalThis section covers What is Optional and the benefits of OptionalHow Optional can help you avoid Null Pointer exceptionExploring the different operations that are part of Optional such as :empty()ofNullable()of()orElse()orElseGet()orElseThrow()isPresent()ifPresent()map()flatMap()filter()Section 14: New Date/Time LibrariesThis section covers new Date/Time Libraries such as LocalDate, LocalTime, LocalDateTimeHow to find the difference between the LocalDate, LocalTime and LocalDateTime using Period, DurationHow to represent the time in the Machine Readable Format using InstantHow to use the TimeZone using the ZonedDateTimeHow to Format the Date using the DateTimeFormatterSection 15: Local Variable Type Inference (LVTI) using varIn this section, we will code and learn about the LVTI feauture to simply local variable declaration using type inference.Section 16: Text Blocks In this section, we will code and learn about the TextBlocks which enhances the power of String in Java.Section 17: Enhanced SwitchIn this section, we will code and learn about the new Switch which is an expression.Switch - as an ExpressionMultiline switch expression using "yield"Enhanced Switch are exhaustiveSection 18 : RecordsIn this section, we will code and explore the record classes concept in Modern Java.Records ClassesCustom Constructors and Validations in Record ClassesObject Equality in Record ClasesSection 19  : Pattern MatchingIn this section, we will code and learn about pattern matching.Introduction to Pattern MatchingRecord Patterns -
